Harold E. Varmus

Harold Eliot Varmus (born December 18, 1939) is an American biomedical researcher and public health administrator distinguished for his pioneering contributions to understanding the molecular basis of cancer. He shared the 1989 Nobel Prize in Physiology or Medicine with J. Michael Bishop for their discovery that oncogenes in retroviruses derive from normal cellular genes (proto-oncogenes), demonstrating that cancer arises from mutations in the host genome rather than solely from viral introduction, a finding that reshaped oncology research. Varmus advanced from faculty positions at the University of California, San Francisco, to leadership roles including Director of the National Institutes of Health from 1993 to 1999, where he expanded extramural research funding and promoted data sharing, and Director of the National Cancer Institute from 2010 to 2015, emphasizing precision medicine initiatives. Between these, he served as President of Memorial Sloan Kettering Cancer Center from 2000 to 2010, fostering interdisciplinary cancer studies.

Harold Eliot Varmus was born on December 18, 1939, on the south shore of Long Island, New York, to Jewish parents of Eastern European descent. His father, Frank Varmus, was a general medical practitioner who had emigrated from near Warsaw, Poland, and briefly attended Harvard College before financial constraints intervened; during World War II, he served as a medical officer in the Air Force and practiced at Jones Beach State Park after the war. Varmus's mother, Beatrice Barasch Varmus, worked as a psychiatric social worker, commuting to New York City, and came from Austrian Jewish roots around Linz; her parents, Harry and Regina Barasch, operated a children's clothing store in Freeport, New York.
